Seahawks rookie tackle James Carpenter has ACL injury

Rookie right tackle James Carpenter suffered a torn ACL in Wednesday’s practice, the Seahawks confirmed on Thursday. He will miss the rest of the season.

Both of Seattle’s rookie starters on the offensive line have suffered season-ending knee injuries in the past week. Rookie right guard John Moffitt suffered a torn MCL and PCL in his right knee in Sunday’s win over the Baltimore Ravens, and was placed on Injured Reserve earlier this week.

Carpenter will likely be replaced by backup tackle Breno Giacomini, who was pushing Carpenter for the starting job in training camp.

Carpenter was the team’s first-round draft pick this season (25th overall). He started each of the team’s first nine games this season after the Seahawks anointed him the starting right tackle on draft day.
